Geranium plant named ‘Pacshorg’

ABSTRACT

A new and distinct cultivar of Zonal Geranium plant named ‘Pacshorg’, characterized by its compact, upright and rounded plant habit; freely branching habit; vigorous growth habit; dark green-colored leaves; freely flowering habit; long flowering period; semi-double bright orange-colored flowers; and good garden performance.

Botanical designation: Pelargonium×hortorum.

Cultivar denomination: ‘PACSHORG’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Zonal Geranium plant, botanically known as Pelargonium×hortorum, and hereinafter referred to by the name ‘Pacshorg’.

The new Zonal Geranium plant is a product of a planned breeding program conducted by the Inventor in Dresden, Germany. The objective of the breeding program is to create new uniform semi-double flowered Zonal Geranium plants with dark green-colored leaves and attractive flower coloration.

The new Zonal Geranium plant originated from a cross-pollination made by the Inventor in Dresden, Germany during the summer of 2005 of two unnamed proprietary selections of Pelargonium×hortorum, not patented. The new Zonal Geranium plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Dresden, Germany in June, 2006.

Asexual reproduction of the new Zonal Geranium plant by vegetative terminal cuttings in a controlled greenhouse environment in Dresden, Germany since January, 2007, has shown that the unique features of this new Zonal Geranium plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Zonal Geranium have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Pacshorg’. These characteristics in combination distinguish ‘Pacshorg’ as a new and distinct cultivar of Zonal Geranium:

-   -   1. Compact, upright and rounded plant habit.     -   2. Freely branching habit.     -   3. Vigorous growth habit.     -   4. Dark green-colored leaves.     -   5. Freely flowering habit.     -   6. Long flowering period.     -   7. Semi-double bright orange-colored flowers.     -   8. Good garden performance.

Plants of the new Zonal Geranium differ primarily from plants of the parent selections in plant vigor and flower color.

Plants of the new Zonal Geranium can be compared to plants of Pelargonium×hortorum ‘Drapin’, disclosed in U.S. Plant Pat. No. 10,561. In side-by-side comparisons conducted in Dresden, Germany, plants of the new Zonal Geranium differed from plants of ‘Drapin’ in the following characteristics:

-   -   1. Plants of the new Zonal Geranium were more compact than         plants of ‘Drapin’.     -   2. Plants of the new Zonal Geranium had larger flowers than         plants of ‘Drapin’.     -   3. Plants of the new Zonal Geranium had fewer flowers per umbel         than plants of ‘Drapin’.     -   4. Plants of the new Zonal Geranium and ‘Drapin’ differed in         flower color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Zonal Geranium plant, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Zonal Geranium plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Pacshorg’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown in 19-cm containers in Dresden, Germany in a glass-covered greenhouse during the summer and autumn and under conditions which closely approximate commercial Geranium production. During the production of the plants, day temperatures averaged 18° C., night temperatures averaged 16° C. and light levels ranged from 15 kilolux to 100 kilolux. Plants were four months old when the photograph was taken and plants were nine months old when the description was taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
